Bug Summary and Steps to Reproduce

Bug Summary:
As part of a project, I have a header-only library split into two sections, one containing some declarations and another containing the implementation. The implementation header is included at the end of the declarations one. When I view the implementation header, I get IntelliSense errors regarding undefined identifiers.

Steps to reproduce:

  1. Make a new project directory with the following files:
  • main.cpp
#include <iostream>
#include "getIpAddress.hpp"

int main()
{
    std::cout << getIpAddress() << '\n';
}
  • getIpAddress.hpp
#pragma once

#include <string>

using IpAddress = std::string;

IpAddress getIpAddress();

#include "getIpAddressImpl.hpp"
  • getIpAddressImpl.hpp
IpAddress getIpAddress()
{
    return "192.168.1.10";
}
  1. When accessing getIpAddressImpl.hpp, IntelliSense should throw the error: identifier "IpAddress" is undefined [C/C++(20)]. However, the code compiles perfectly well (using g++ 14.1.1, g++ -o main main.cpp).
  2. Restarting IntelliSense for the active file (getIpAddressImpl.hpp) does not solve the issue.
  3. However, I've noticed that changing the extension of getIpAddressImpl.hpp from .hpp to .tpp (used for template implementations), and then changing back to .hpp solves the problem either immediately or after an IntelliSense restart of the active file. Afterwards, I cannot reproduce the error anymore without deleting all files and rewriting them again. This "fix" does not work in my original, larger project (probably because the implementation file in the original project contains include statements that cannot be resolved anymore once the extension is changed, since the .tpp file is identified as C instead of C++?).

Expected behavior:
Intellisense correctly identifies IpAddress as an alias for std::string.

... and a couple of Python extensions.

In my original work project, disabling the Meson extension and re-enabling it solves the issue. However, the way to do this is not reproducible: sometimes I have to delete the settings.json file produced by the Meson, sometimes it recovers just by itself (given enough time), sometimes I have to change the c_cpp_properties.json. However, disabling the Meson extension does not solve it in the reproducible example above (makes sense, since I'm not even using Meson).
